I drove this car about 1200 kms ...it has been satisfying till date with good diesel commuter.I got an average of 18-19 in city conditions. But on highway it responded well with economy of about 23-24 kmpl. The car is pretty descent in terms of controllability at higher speeds and cruises nicely after 200 rpm.overtaking is fun without any gear shift.air condition is superb and cools the cabin rapidly.sound system is very nice and other functions like voice command navigation ac control are pretty easy to use. But only draw back is tata should have given retractable mirrors.and reverse camera.
